<array-member language __languages>
returns the index of the language in the __languages variable and a null
string if this language is not found.
   #use wml::std::lang
   <lang:new id=en>
   <lang:new id=fr>
   <lang:new id=de>
   foo<array-member fr __languages>foo
   foo<array-member it __languages>foo
